Platinum, pt, is one of the rarest of the metals. worldwide annual production is only about 130 tons. platinum has a density of 21.4g/cm3. if thieves were to steal platinum from a bank using a small truck with a maximum payload capacity of 900 lb, how many 1 l bars of the metal could they take? (a) 19 bars(b) 2 bars(c) 42 bars(d) 1 bars(e) 47 bars

(A) 19 bars

Explanation:

First off, we calculate the mass of platinum contained in one 1 L bar. To do that we convert 1 L into cm³ -1 L equals to 1000 cm³-.

21.4 g/cm³ * 1000 cm³ = 21,400 g

Each bar of platinum weighs 21,400 grams.

Now we convert the maximum payload capacity of the truck, into grams (1 lb equals to 453,592 g):

Then we divide the weight of one bar by the maximum payload capacity:

408232.8 / 21400 =19.09

Thus the thieves could carry 19 1 L bars

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

they are all solids.
